The cotton stickiness problem in spinning is highly complex as stickiness may be caused by various types of contamination: kernel, traces of oil, etc; physiological sugars due to the plant; and honeydew, sugars produced by homoptera, and aphid Aphis gossypii and the whitefly, Bemisia tabaci. The most serious type of stickiness that causes the worst problems in spinning is cotton contamination by honeydew. It is found on the plant and at various stages of fiber processing into yarn. The thermodetector SCT measures the stickiness of cottons polluted by insect honeydew. This paper shows the different types of honeydew recovered from a sheet of aluminium foil after testing on the thermodetector. In March 1994, the International Committee on Cotton Testing Methods (ICCTM) of the International textile Manufacturers federation (ITMF), adopted the SCT thermodetector method as the reference method for assessing honeydew stickiness of cotton. The SCT thermodetector and its methodology have been standardized as CIRAD in order to reduce the variation sources which can have an effect on the number of sticky points.
